The concept of morphing geometry to control and stabilize the flow has been proposed and applied in several aeronautic and wind turbine applications. We studied the effect of a similar passive system applied on an axial fan blade, analyzing potential benefits and disadvantages associated to the passive coupling between fluid and structure dynamics. The present work completes a previous study made at the section level, giving a view also on the three-dimensional (3D) effects. We use the numerical computation to simulate the system, which defines a complex fluid–structure interaction (FSI) problem. In order to do that, an in-house finite element (FE) solver, already used in the previous study, is applied to solve the coupled dynamics.
